ATOMIZER.

SPECIFICATION forming part of Letters Patent No. 648,656, dated May 1, 1900.

Application filed March 17, 1899. Renewed March 8, 1900. Serial No. 7,931. (No model.)

To all whom, it may concern:

Be it known that I, ALLEN DE VILBISS, a citizen of the United States, and a resident of Toledo, Lucas county, State of Ohio, have invented certain new and useful Improvements in Atomizers; and my preferred manner of carrying out the invention is set forth in the following full, clear, and exact description,

terminating with claims particularly specifying the novelty;

. This invention relates to at0mizers; and the object of the same is to produee'an improved atomizer which can be manufactured at a minimum of expense and yet will meet all requirements demanded of the ordinary instrument.

To this end the invention consists, primarily, in the simple means of connecting and supporting the pipes and in the specific form of nozzle employed, and, secondarily, in details of construction which cooperate therewith to produce an efficient whole.

, The same is fully described in the [follow ing specification and shown in the accompanying drawings, wherein Figure 1 is a general side elevation of the atomizer with certain parts in section; and

Fig. 2 is an end view in detail, showing hall f the cap in full lines and half ot the intcrior portion ol' the nozzle in section.

Similar numbers refer to the same parts in both views.

Referring by numerals to the said drawings, 1 is a bulb or any other equivalent source of air-supp] y, and 2 is the head of the main tube 3, onto which the delivery-pipe 4 'from the air-supply is fastened. At some suitable point within its length the body of' this (preferably metallic) tube is pinched or depressed from its upper side, as at 5, sons to close the opening therethrough and form a partition or dividing-wall between its end portions. At either side of this wall are inlet and outlet apertures G and 7, respectively, and formed inthc lOWcl side of the tube adjacent the outlet-aperture is a third aperture 20. At one end is the head 2, above men tioncd, and at the other end the upper side of the tube is depressed, as at 8, so as toleave an outlet-port .J at the lower side only 01' the tube at this end.

The numeral 10 designat s the reservoir,

(usually a bottle, as of glass,) and 11 is its neck, whereon is mounted the stopper 12,.having a transverse opening 13, of a size to receive the tube 3. This reservoir is of any desired size, shape, and material, and its stopper is only necessarily constructed in such a manner as to cooperate with the parts already described.

Secured to the tube S'is the liquid-pipe, consisting of the member 21, with an aperture 22 in its end registering with that numbered 20 in the tube 3, and the member 23, extending from near the bottom of the reservoir 10 upward and adj ustably secured at 24 (as by threads) to said member 21.

Obviouslyother details of construction may be employed without departing from the spirit .of my invention.

In connection with the above parts I preferably employ a nozzle, constructed as now set forth.

30 is a cap substantially square on its exterior and having an axial outlet 31 in its closed end 32, while this cap ison its interior of a shape to fit upon the end of the round tube 3 with some considerable degree of friction. may be of any desired size, shape, and material, and considerable change in the exact construction thereof may be made Without departing from the general idea.

In construction and use the reservoir or bottle 10 is first brought intoplay and filled. The main pipe 3 is then inserted through the opening in the stopper, the liquid-pipe 21 23 brought into place and connected therewith, and the stopper fitted upon the neck. The source of air-supply is then attached, and, finally, the cap is adjusted to the delivery end of the main'tube 3. The body or reservoir being partially filled with the liquid from which it is desired to atomize the contents to the patient, pressure is applied to the bulb or other source of air-supp] y. This drives air into the tube 3 through the inlet 6 into the body 10 upon the liquid therein, out the outlet 7, and along the tube 3. thus set up upon the liquid standing within the bod ylO will causeasmall portion thereof to rise through the liquid-pipe 21 23, which, passing out the aperture 20, will mingle with the air fiowingalong the tube 3 and be de- This cap, like other parts of my device,

The pressure IOO livered out the nozzle. Here again the specific construction of parts is'advantageous, for as the mixed air and liquid passes out the port 9, which is atthe lower side of the tube 3, it is trapped within the chamber formed by the cap 30 beyond the p rt- 9 and is delivered in a fine spray at and through the outlet 31, and any drops or particles of liquid that would under 0 linary circumstances accumulate within the cap 30 or at the outlet-port 9 are dissipated and disintegrated by the blast of air. The construction of parts is intended to be such that the space within the cap beyond the port permits the air and liquid to he socomming'led that when passing outthe outlet 31 it will he in a perfect spray. Furthermore, this space is so small and trivial that no apprecia le amount or liquid can remain therein without being hiown out of the noiile by the blast or air therethrough. 1 preferably construct the cap with a square or angulat exterior in order that it can be adjusted axially upon the tribe 2 to regulate its action in eonnectioii with the dehverypert 9 thereof. The adjustable eon section between the members 21 and 23 of the liquid-pipe is obviously for the purpose of permitting the lower member to be moved to'a proper depth within the liquid in the bottle or to be replaced by other members when desired.

I call especial attentionto the'fact that the reservoir 10 has a neck 11 or glass and the stopper 12 is of lightsheet metal, (preferably brass,) so shaped andpreportionedthat when slipped onto said heels it accommodates itself to all irregularities therein,- so as to make a substantially if not perfectly air-tight joint between these parts. This detail of construction I consider essential in an atomizer, for the reason that while some air-tight joint must be formedbetween the neck and stop per this small arrangement accomplishes the end in view in a quick and efficient manner without the use of a cork or its equivalent and yet leave the arts ca able of separatien when desired,

What is claimed as new 'lS-;'- i q I 1 In an ato izemhe combination with the IiqHid-rcseiVGirhaVing an opentopped neck,

and a stopper fitting thereon and having a 1 transverse opening; of astraight air-tube extending transversely and completely through said opening and having three apertures within the stopper, a source of air-supply at one end of the tube, a nozzle at the other end, a partition within the tube between two of its apertures, and a liquid-pipe within the reservoir leading tothe third aperture, all as and for the purpose set forth. v

i 2. In an atomizer, the combinationwiththc liquid-reservoir, a stopper therefor having a transversethrough-opening, and 1. liquidpipe; of a metallic air-tube extending through said opening and having the material thereofi depressed from its upper side to close its body, inlet and outlet apertures in the lower side of this tube on opposite sides of said depression, connections between the liquid-pipe and airtube, and at opposite ends of the latter a source of air supply and a nozzle, all as and for the purpose set forth. 7

8. In an atomizer,the combination with the liquid-reservoir, the single tube crossing its upper end and having in, its under side air inlet and outlet and liquid-outlet, and the bulb and nozzle; of aliquid-pipe comprising an upper member secured at right angles to the lower side of theair-tube over its liquidoutlet and a lower member screwed to the uper member and standing within the liquid, as and for the purpose set forth.

4-. In an atomizer, the combination with the main tube having an outlet-port eccentric to its axis, the reservoir, and means for forcing mixed air and liquid along said tube; of a cap angular on its exterior and cylindrical interiorly so as to fit adj ustably on the dolivery end of said tube, the closed outer end of said cap having an axial and central exitopening, substantially as described.

5. The combination with the main delivery tube of an atomizer depressed at its upper the purpose set forth.

In testimony whereof I have hereunto subscribed my signature this 14th day of March, A. D. 1899.
